互联网流量的预测增长使得运营商和行业关注网络的功耗，并且对以更节能的方式规划和操作网络的替代方案感兴趣。OFDM技术的引入及其弹性带宽分配的特性为光网络的运行开辟了新的前景。在本文中，我们比较了弹性带宽CO-OFDM网络和固定网格WDM网络的网络规划问题。我们强调了带宽弹性和选择不同调制格式在能源效率方面提供的好处。
The forecasted growth in the Internet traffic has made the operators and industry to be concerned about the power consumption of the networks, and to become interested in alternatives to plan and operate the networks in a more energy efficient manner. The introduction of OFDM, and its property of elastic bandwidth allocation, opens new horizons in the operation of optical networks. In this paper, we compare the network planning problem in an elastic bandwidth CO-OFDM-based network and a fixed-grid WDM network. We highlight the benefits that bandwidth elasticity and the selection of different modulation formats offer in terms of energy efficiency.
